N FHUI E INVENTOR. CARL MS COMBS BY 7L ATTORNEYS ALIGNING DEVICE FOR SPINDLE ASSEMBLY This invention relates to an aligning device, and more particularly to a device for aligning spindles on a spinning or twisting frame.

In order to obtain uniform yarn packages which are wound on spinning or twisting frames it is necessary that the spindle blade be in proper alignment with the ring during the winding operation. Heretofore, it has been customary in setting the spindle in the box rail to mount the base in the rail in such a position that it was centered with reference to the ring when closest to the rail. Then the ring was moved to a location at its greatest distance from the rail and an attempt was made to center the upper part of the blade in the ring by placing cardboard or paper shims between the base and the rail. This is a slow, tedious and inaccurate method of procedure.

Accordingly, it is an important object of the present invention to provide a device for aligning spindles on spinning and twisting frames.

Another important object of the present invention is to pro vide a device which can be readily mounted on a spindle as sembly for centering the upper part of a spindle blade in the rail so that uniform packages of yarn and the like, can be wound thereon.

Another important object of the present invention is to provide a simple and inexpensive device which can be mounted on conventional spindle assemblies which eliminates the necessity of shims to change the position of the axis of the base with reference to the rail.

The construction designed to carry out the invention will be hereinafter described, together with other features thereof.

The invention will be more readily understood from a reading of the following specification, and by reference to the accompanying drawing forming a part thereof, wherein an example of the invention is shown and wherein:

FIG. 1 is an enlarged plan view illustrating a device which can be mounted on a spindle assembly for aiding in aligning the spindle relative to a desired axis,

FIG. 2 is a side elevational view of a spindle assembly with the device mounted thereon, and

FIGS. 3 through 38 are plan views illustrating the spindle in various positions of alignment relative to the ring.

The drawing illustrates a device for aligning a spindle assembly on spinning and twisting frames. The spindle assembly has an elongated base portion A adjacent the lower end, an elongated blade B defining the upper end of the spindle assembly and an intermediate body portion between the base portion A and the blade B. The spinning frame includes a conventional rail C having a hole therein, through which the base portion B extends. Threads are carried on the base portion below the rail C and a nut is threaded on the threads for securing the base portion to the rail. An aligning member D is carried on the intermediate body portion of the spindle assembly above and closely adjacent the rail C. Aligning member D extends radially from the spindle and has a plurality of adjustable means E circumferentially spaced around the spindle assembly for tilting the spindle assembly relative to a desired vertical axis for aligning the spindle assembly on the axis. Thus, adjustable means E can be varied to align the spindle assembly.

Referring more particularly to FIG. 2 of the drawing, there is shown a conventional spindle assembly which includes a base portion A which extends below the conventional rail C on a spinning or twisting frame. The base portion A has a threaded portion 10 thereon, upon which a nut 1 l is threaded to secure the base portion A to the rail C. Positioned between the nut 11 and the bottom of the rail C is a washer 11a. The base portion A extends through a hole in the rail (not shown) upwardly and terminates with the bolster 12 which has a conventional roller neck bearing (not shown) through which the spindle shaft 12a extends and is partially supported thereby. A collar 13 is integral with the base portion and is provided for supporting a doffer guard (not shown). As can be seen, the collar 13 is located above the spindle rail C. The conventional spindle which terminates in the elongated blade B is supported on the base A with the spindle shaft 12a extending therein. A bobbin 14 is shown on the blade B and .yarn is wound on the bobbin as the spindle is rotated on the base A. The spindle has a reduced diameter portion 15, generally referred to as the whorl" around which a tape passes for driving the spindle.

Positioned between the collar 13 and the rail C is the aligning member D. The aligning member D has a hole extending therethrough which is substantially the same diameter as an intermediate body portion 15a so that it can be pressed to fit thereon. The aligning member D extends radially from the intermediate body portion, and has a plurality of adjusting means E circumferentially spaced around the spindle assembly for tilting the spindle assembly relative to a desired vertical axis. The adjusting means E includes set-screws 16 which are carried in threaded holes 17 in the aligning member D. The bottom of the set-screws 16 are in contact with the rail C. As can be seen, in FIG. 1 there are three holes in the aligning member D which are equally spaced around the spindle assembly. By rotating the screws 16 to raise the aligning member D relative to the rail C the spindle assembly can be aligned to a desired axis wherein the spindle blade B is centrally located relative to the travel of the ring 18.

In operation the base is located in the rail 13 so that it will be as near center as pomible to the ring 18 in which a traveler rotates while the ring is at the bottom of its stroke. The nut 11 is threaded on the threaded portions 10 of the base until it becomes fairly snug against the washer l2 abutting against the rail C. A spindle set 19, which takes the form of a collar, is placed on top of a bobbin or, in some cases, directly on the spindle blade B for aiding in centering the blade B relative to the ring 18. FIGS. 3A through 38 show the spindle set 19 carried on top of the spindle blade in various positions of alignment.

After the spindle blade has been centered with the ring at the bottom, the ring rail is then moved to the top of the stroke. Ifthe blade is still out of alignment for example, in the position shown in FIG. 3, the set-screw 16 in the lower right-hand corner is tightened down to move the blade B slightly beyond the center axis of the ring-rail. The ring-rail is again moved back to the bottom of the stroke and centered by tapping the spindle base A to bring the blade B back on the center axis of the ring 18. The ring 18 is again moved back to the top of its stroke and minor adjustments of the screws 16 are made in order to bring the blade in the position illustrated in FIG. 3A wherein the blade is in proper alignment relative to the ringrail 18.

The aligning member D illustrated in FIG. 2 is mounted on a conventional spindle base A. However, it is to be understood that it could be cast integral with the spindle base A, and it is possible to eliminate the collar 13 which supports the conventional dofier guard by mounting the doffer guard directly on the aligning member D.

As can be seen, the aligning member D eliminates the necessity of shimming with paper, and as a result, minimizes the time required for aligning the spindle assembly, since the nut 11 does not have to be loosened as is the case in placing the shims between the collar 13 and the rail C.

While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
